Eugenol is one of the most important clove-based aroma chemicals used across fragrance, flavour, oral-care, pharma, and home-care industries. Known for its warm spicy note, functional antimicrobial properties, and consistent performance in formulations, it plays a major role in both natural and synthetic perfumery.
As a leading chemical manufacturing and trading partner for B2B clients, Chemicalbull Pvt. Ltd. supplies high-quality Eugenol for applications where aroma quality, functional benefits, and purity matter.
This blog explains everything about Eugenol—its structure, solubility, uses, benefits, fragrance behaviour, industrial applications, and commonly searched differences.
Eugenol is a phenolic compound recognised for its strong clove-like smell and antimicrobial activity.
It is naturally found in many spices and aromatic plants.
Clove buds (primary source), cinnamon leaves, nutmeg, basil, bay leaf, and allspice.
These natural sources contribute to the global demand for Eugenol as a fragrance and functional ingredient.
Eugenol contains:
A benzene ring
Phenolic hydroxyl group
Methoxy group
Allyl chain
Functional Group Function
Phenol (–OH): Provides antimicrobial activity
Methoxy (–OCH₃): Enhances aroma and reactivity
Allyl chain improves volatility for perfumery
These chemical features make Eugenol suitable for complex fragrance blends, oral-care formulations, and pharma use.
Eugenol solubility plays a major role in formulation development.
Soluble in: alcohol, oils, organic solvents
Partially soluble in: water
This allows easy blending into perfume oils, creams, gels, flavours, mouthwash bases, and topical products.
